参考解析：

推理判断题。根据第三段第七句“However, Fitzgerald’s problems with his wife Zelda had an effect on his writing.”可知如果他不与妻子的关系破裂，他可能写出更多的作品，所以C项正确。根据第一段最后一句“Then he had to make some money to impress her.”他必须赚些钱来打动她，可知当他遇到塞尔达的时候他没有钱，所以A、B项错误；根据第三段最后两句“While his wife was in hospital in the United States, he got totally addicted to(沉迷于)alcohol. Sheila Graham, his dear friend helped him fight his alcoholism”可知当他的妻子住院时，他完全沉迷于(沉迷于)酒精。是他的朋友希拉·格雷厄姆帮助他戒酒，而并不是他帮助他的朋友戒酒，所以D项错误，故选C。
